EW has learned CBS has enlisted Beverly D’Angelo and Colin Hanks in a pair of guest star roles on an upcoming episode of sophomore comedy Mom, which stars Anna Faris as sober single parent Christy and Emmy winner Allison Janney as her razor-sharp mother Bonnie.

D’Angelo will play Lorraine, the ex-wife of Christy’s father Alvin (Kevin Pollak), who comes back to town and into his life again just in time to complicate his still-sensitive relationship with his other ex Bonnie.

Hanks, meanwhile, will play Andy, a potential love interest for Christy whose idea of a fun night isn’t exactly what she expects.

Hanks and D’Angelo’s episode will air in early 2015. Mom’s second season premieres Thursday, Oct. 30 at 8:30 p.m. on CBS.
